Nearly three years ago the writer showed that acid potassium and acid sodium phthalates may be used with advantage as standards in volumetric analysis. They can be easily prepared in a state of great purity, they have large molecular weights, and the acid potassium salt has the distinct advantage of absence of water of crystallization. So little work on these salts has been done and so limited is the knowledge of them that it was thought desirable to make further study of the properties and value as a standard of at any rate the potassium salt.
